Answer:
One
Explanation:
Covalent bond or molecular bond is a type of chemical bond which is formed by the mutual sharing of valence electrons between two atoms. These valence electrons are often the unpaired electrons present in valence shell of an atom.
Examples:
Element # of Electrons Electronic Config. # of Covalent Bonds
H 1 1s¹ 1
C 6 1s², 2s¹, 2px¹, 2py¹,2pz¹ 4
N 7 1s², 2s², 2px¹, 2py¹,2pz¹ 3
O 8 1s², 2s², 2px², 2py¹,2pz¹ 2
Result:
As Hydrogen atom contains only one electron in its valence shell, therefore it will only make one single covalent bond with either Carbon, Nitrogen or Oxygen.
